TITLE: A 54 year analysis of articles from Mpilo Central
Hospital, Bulawayo, Zimbabwe-168 articles cited 999 times. (Article,
English)
AUTHOR: Masukume, G

SEARCH TERM(S): CITED item_title
ABSTRACT: PubMed and Google Scholar were searched to obtain
articles originating from Mpilo Central Hospital, Bulawayo, Zimbabwe -
1958 to August 2011 (54 years). 168 articles cited 999 times were
retrieved giving about 6 citations per article. Analysis of publication
trends over time as well as publication avenues is made. The full
research dataset for this study is shared. This study adds to the body of
knowledge on teaching hospital research performance assessment
particularly in low-income settings, a topic with few studies. Africa
needs data on research.

ABSTRACT: Chagas disease is a chronic, tropical, parasitic disease,
endemic throughout Latin America. The large-scale migration of
populations has increased the geographic distribution of the disease and
cases have been observed in many other countries around the world. To
strengthen the critical mass of knowledge generated in different
countries, it is essential to promote cooperative and translational
research initiatives. We analyzed authorship of scientific documents on
Chagas disease indexed in the Medline database from 1940 to 2009.
Bibliometrics was used to analyze the evolution of collaboration
patterns. A Social Network Analysis was carried out to identify the main
research groups in the area by applying clustering methods. We then
analyzed 13,989 papers produced by 21,350 authors. Collaboration among
authors dramatically increased over the study period, reaching an average
of 6.2 authors per paper in the last five-year period. Applying a
threshold of collaboration of five or more papers signed in co-
authorship, we identified 148 consolidated research groups made up of
1,750 authors. The Chagas disease network identified constitutes a "small
world," characterized by a high degree of clustering and a notably high
number of Brazilian researchers.

ABSTRACT: We report on the activities of the European Dry Grassland
Group (EDGG) during the last year, namely the 8th European Dry Grassland
Meeting in Uman', Ukraine in June 2011, the 3rd EDGG Research Expedition
in Bulgaria in August 2011, the 4th EDGG Research Expedition in Sicily in
April 2012, as well as the completed and forthcoming EDGG-coordinated
special features in international journals. Then we provide a brief
bibliometrical analysis of the Dry Grassland Special Features in Tuexenia
since 2005. The 32 contributions of the years 2005-2011 constituted
approx. 17% of the overall content of Tuexenia in this period. Including
this 7th Dry Grassland Special Feature, sixty-one authors from 12
countries have contributed to these Special Features, guest-edited by
yearly changing teams from a total of 16 guest editors. In the years with
statistically reliable data, contributions in the Dry Grassland Special
Features have been cited approximately four times as much as regular
Tuexenia contributions. It is likely that this fact together with the
internationality of the Special Features has contributed to the final
inclusion of the journal in the Web of Science in 2011. Finally, we
introduce the four research articles of this 7th Dry Grassland Special
Feature. Two of them are focusing on vegetation change and restoration
issues of cryptogam-rich sand dunes in the Netherlands and calcareous
grasslands in Bavaria (Germany), respectively. The others, dealing with
siliceous grasslands in Hesse (central Germany) and the results of EDGG
Research Expedition 2009 to Transylvania (Romania), focus on syntaxonomy.

TITLE: The Statistics of Urban Scaling and Their Connection to

KEYWORDS+: DISTRIBUTIONS; CITIES
ABSTRACT: Urban scaling relations characterizing how diverse
properties of cities vary on average with their population size have
recently been shown to be a general quantitative property of many urban
systems around the world. However, in previous studies the statistics of
urban indicators were not analyzed in detail, raising important questions
about the full characterization of urban properties and how scaling
relations may emerge in these larger contexts. Here, we build a self-
consistent statistical framework that characterizes the joint probability
distributions of urban indicators and city population sizes across an
urban system. To develop this framework empirically we use one of the
most granular and stochastic urban indicators available, specifically
measuring homicides in cities of Brazil, Colombia and Mexico, three
nations with high and fast changing rates of violent crime. We use these
data to derive the conditional probability of the number of homicides per
year given the population size of a city. To do this we use Bayes' rule
together with the estimated conditional probability of city size given
their number of homicides and the distribution of total homicides. We
then show that scaling laws emerge as expectation values of these
conditional statistics. Knowledge of these distributions implies, in
turn, a relationship between scaling and population size distribution
exponents that can be used to predict Zipf's exponent from urban
indicator statistics. Our results also suggest how a general statistical
theory of urban indicators may be constructed from the stochastic
dynamics of social interaction processes in cities.

TITLE: Cost management under the agribusiness production chain

Scientific Publications
ABSTRACT: The market globalization and the resulting competition
affect the growth and survival of companies through obtaining competitive
advantages, primarily based on quality and products prices. The
agribusiness, with its commodities, is particularly subject to this
environment. The management of production chains is an alternative to
reduce costs and runs with joint efforts of companies in the same sector.
This paper aims to identify the aspects that characterize the
publications about management costs of agribusiness production chains.
The study presents qualitative and quantitative evidence. It was
developed a literature search, content analysis and use of descriptive
statistics. The study, developed during the second half of 2010, was
based on a review of 69 articles published between 1999 to 2009 by
editions of the Brazilian Congress of costs, the journal
Costs at Agribusiness On line; Brazilian Business Review and Rural
Organizations & agribusiness. The study found little on the exploration
of the theme in the period analyzed, indicating that there is still ample
room for research in agribusiness.
